The screw-rod 34 operates in a threaded bore 36 in the body portion 30, as shown in Fig. 5, and may be provided with a handle portion 37 for its operation. The jaw member 33 .is prevented fromI lateral displacement by a guide member 38, adjustably secured to the working member by a bolt 39 and having a projecting portion 40, between which and side ofthe fixed/portion of the jaw operates a projecting portion 41 of the jaw member 33.

from its engaging part. f

The Working member is also provided with means whereby to adjust the dieeblank 31 toward the table or matrix, which means may comprise an adjusting-screw 42,1working in a threaded aperture in the body por-v tion 30 'and whose end 'member engages a small block 43 rand by -advancing the latter thewmovement of the screw will move the blank outward toward the matrix'.

The table .on each side of the matrixfsupj porting means is provided with ahard'ened iplane bearing-surface 44, and the working accurate movement.

member 13 is provided with curved portions correspondingly disposed to engage and roll on v.these bearing-surfaces ofthe table, all

other portions of the working member being sufficiently* removed from the table to not interfere with such movement, whereby the working member may swing through a short arc, asy indicated in Fig. 6. These two pairs of engaging portions are preferably made of very hard metal to prevent wear and insure These portions of the workingV member may comprise hardened pieces 45, suitably set in the body portion 30. The bearing portions 45 are located on opposite sides of thefblank-clamping meansvof the `working membenas indicated in Fig.` 5, andl upon adJusting the blank, which may have an end surface curved somewhat similar to4 that of the bearing-blocks'45, so that its 'surface is insubstantial l alinement with these curved surfaces', the blank may be caused to have'a rolling engagement with thematrix 15.

s'uitable yhandle 46 extends upward froml the working member 13 for rocking the same. vi'Upon the *die-blank"and matrix being relal tively adjusted to bring an engraved characl ter in the matrix to register and engage with the'intermediate portion of the blank, and thereupon vrolling the blank over the matrix and properly feeding it downward to engage "the matrix .the `character engraved in the matrix will be reproduced in relief'on the engaging surface of the blank; but to produce this effect kit is'practically necessary` to roll y the blank a number of times back and forth across' the matrix, and means should be provided to insure the blank always returningto the same position. relatively to the matrix and to prevent any shifting the blankecar- .rying .member 1f thecurvedface of the bearing-blocks 45 are circular-that is, are sectors of circles-the movement of the working member will be cycloidal. One means of producing such a movement of the Working I member is to provide guiding members or y surfaces, one of them or one set of them being secured to the table, and the other one or set to coperate'therewith being fast on the working member. 41n the present instance a pair of' members 47 are provided having cycloidal faces 43, andsuitable guide mem-A bers are provided on the working member,"

having surfaces for engaging therewith, whose position is fixed relative to the working mem ber; but in order to reduce friction to a minimum these guide-surfaces on the working member `may be formed by rollers 49,' ar.`A

ranged to engage the faces'48 of the guide? teeth of the guide members 47, respectively. y

One set of such guiding means is shown' in Fig. 6 but this arrangement is duplicated at the other end of the apparatus, as -indicated in Figs. 1 and 5f The feeding or advancement 'of the dieblank would have a tendency to raisethe working member, so that the engaging blocks 45 would not properly operate on their supporting-surfaces on the table and would further tend to separate the cycloidalnguiding means.- To-'overcome this objection, suit-- able pressing means are provided in order to press or retain the 'working member in its i' proper path of movement or at least to inroo sure its beingin such position .at the middle part of its rocking movement when the' dieblank is registering with the character of the I matrix.` It is, however, ldesirable that the working member may be allowed a small amount of play or movement from the table at one or both sides of said intermediate position for the purpose of permitting an advancement or feeding `downward ofthe` die' blank from time to time as its end is 'cornpressed by the matrix to form the characteron the blank in relief. The' pressing member in the present instance is shown asc'om- IIO prising two frames, one. at each end of theapt `A i paratus. Each frame may :comprise'cross may beadjustable therein to compensate for ywear and to facilitate adjustment. At eachl with. the rocking surfaces 45. j On the b ottom face of each of the cross-pieces 50 is arranged ia similar cylindrical groove 55, which grooves are symmetrically arranged on these members Pins 56 of a size to fit the cylindrical I I 5 members' 50 and l51, that are lconnected by e tie rods or bolts52, passing through apertures" at the ends of the said members. and which.

grooves 54 are placed therein, and thereupon the frames are placed with the grooves 55 resting on the upper portion of these pins 56. The adjacent portions of the grooved members are suliiciently cut away to permit of a swinging movement of the frames, as shown in Figs. 2 and 6. A similar swinging connection is provided between the lower crossplaces 5l of the frames and thevtable, suitable pins 58 being arranged between similarly located grooves 57 whereby when the working member is rocked, causing the frames to swing upward, movement of the frames upward -is yprevented beyond that of the arc swung from the axis of the pin 58 and passing through the axis ofthe pin 56. These frames are so designed that the axis of the pins 56 is located in a circle of which the curved faces of the bearing-blocks 45 are a portion`that is, this axis is removed Jfrom the said curved face for the distance of a diameterof a circle coinciding with the said curved faces, and the axis of the pins 58 is preferably arranged at,

substantially the same distancehthat is, equal to said diameter-below the said curved faces when the working member is in its intermediate or upright position.

rlhe cross-pieces 50 are so adjusted that when the working member is in the intermediate upright position of Fig. 2 the frames will cause the working member to press very strongly against the bearing-faces 46, and consequently will force the die-blank when properly adjusted into intimate engagement with the matrix but when theworking member is rocked by means of the handle 46 to either side of said position this engagement of the working member with the table is somewhat lessened. It will be seen that the axis of the 4upper pin 56 willdescribe a circular curve or arc whose center is that of the pin 58-that is, it would describe such a curve if the 4pressing members were pivotally supported on the pins 58. Now the pins 56-if considered as a fixed part of the working member 13 would lie in a circle with which the rolling faces of the members 45 coincide and would move through a path that is a true cycloid, which curve is indicated in Fig. l by the broken line 60, while the arc, whose center would be that of the pin 58, considered as fast to the table, is indicated by broken line 6l. The cycloid and the circular curve by the above arrangement practically coincide in the axis of the pins 56 when the working member is in the upright position; but when this member is swung to either side, since these two curves diverge a short distance beyond said position and since the cycloidal path is above the circular path, the pins 56 will be permitted to approach nearer to the pins 58, and therefore provide a slight amount of play or lost motion between these pivotal connections of the frames.l By reason of this construction when the working members swing to one side the die-blank canl be advanced a slight distance, which will tend to slightly separate the working member from the matrix and table and produce tension in the pressing-frames; but upon the working member being swung to the upright position this tension will increase by reason of the coincidence of the two curved paths just described, and the die member will be compressed until its surface engaging that of the matrix will be in alinement with the engaging surfaces of the bearing-blocks 45. It is found desirable to previously give a curve to the matrix-engaging end of the die-blank of smaller radius than that of the bearingblocks 45, so that the blanks will have practically no engagement or compression beyond a short distance each side of its character-receiving portion.

Having thus described this invention, I claiml. In a rolling-press, the combination'of a member arranged to support a matrix thereon, a member arranged to carry a die-blank, guiding means arranged to cause the dieblank to have a rolling movement over the matrix when one of said members is swung relative to the other member, and a pressing means pivotally connected to both said members and arranged to press the die-'blank against the matrix.
